MOP.

Specification of letters Patent.

Patented June a, 1918.

Application flle d January 25, 1917. Serial No. 144,348.

To all 901mm z'atmay concern: I

Be 1t known that I, Aueus'r NnLsoN, a c1t1zen of the United States, residing at Minneapolis, in the county ofI-Iennepin and State of Minnesota, have invented certain same having a cylinder and piston attachment for d scharging water onto the floor or for taking up the water fromthe floor, at W111. The term mop is used ina broad sense. The mop, as constructed, however,

preferably includes a scrubbing brush, as

aerwen as a scraper blade.

The preferred form of the improved mop 1s illustrated in the accompanying drawings wherein like characters'indicate like parts throughout the several views. Referring to the drawings:

Figure 1 a plan view of theimproved mcip; F 1g. 2 1s a section, on the line 2--2 of Fig. 3 is an enlarged section on the same line as Fig. 2, but showing only the lower portion of the mop structure; and- Fig. 4.- is a side elevation of the parts shown in Fig. 3.

The mop head is hollow and preferably in the form of a cylindrical tube 5 having, at its central portion an internally-threaded cap6 with an axial port 7. This cap 6 is preferably screwed onto the lower end of a pump cylinder 8, which at its rear end, has a head 9 formed with a long projecting stem 10 that affords a convenient handle for the mop.

Working within the cylinder 8' is a piston 11 having a long rod 12 that projects through the tubular stem 10, so that its outer end may be engaged by one of the hands of the operator, while his other hand grips the tubular stem of handle 10.

On the longitudinal line 'of its outer portion, the mop head 5 is formed with water ports 13. The ends of the said head 5, of course, are closed.

The numeral 14 indicates a heavy but flexible rubber scraper blade, the u per edge of which is attached to the tube 0 the mop head 5; and the numeral'l5 indicates an auxlhary" scraper blade, preferably of raw hide, or leather. The upper edges of the scraper blades 14 and 15 are connected together and, fastened to the top of the mop head 5 by suitable screws 16. The said blades 14. and 15 respectively, are formed w1th water orts 17 and 18, the latter of which are 0 much greater diameter than the former. These portsv 17 and 18 are so located, in respect to each other and in respect to the water ports 13 of the mop head that when the blades are forced against the head and onto the floor, as shown in Fi 1, all of the said .ports 13, 17 and 18 wil be in registration, so that Water may be dislcharged from or down into the said mop head, at will.

The numeral 19 indicates a' scrubbing brush which, as shown is rigidly, but -de-;

tachably secured the mop head *5, by.

meansof screws 20.

The preferred manner of using this mop is asfollows: While the piston 11 is loweredj-in the cyl inder, the, mop head may be dipPed into clean water or suds water contained in a pail, or other receptacle, and;,,;this water may be, drawn into the cylinder; by pulling the piston outward. Then -'the water may be sprayed onto the floor. where desired I while the mop is raised, simply by giving thepiston a downward movement 1n the cylinder, the water, of course being dis charged through the ports 13, 17 and 181 Thenby theuse of the brush 20, the floor may be scrubbed and then, by using the blade 14 as a scraper, as shown in Fig. 3,

'while drawing the mop rearward, the water on any particular part of the floor may be collected. The water may then be drawn back into the cylinder by givin the piston an outward movement in the cy inder while the mop is being forced forward in the position shown in Fig. 4. When the mop is forced forward, as shown in Fig. 4., the water forced ahead of the scraper, will run to the relatively larger ports 18, and by the latter, will be directed to the ports 17 and thence to the ports 13, so that the water W111 be rapidly collected and drawn into the cylinder. This-dirty water may then beejected into a catch pail or other receptacle, simply by giving the piston another downward movement of the cylinder.

With this improved mop, the best kind of without producin scrubbing can be rapidly done without requiring the operator, atany time, to get upon his knees, and moreover, both the clean and dirty water can be handled without re quiring the operator to put his hands in the Water. Moreover, mopping can be :done splashing of walls or easements. The e cieney of the device has been demonstrated in actual practice.

What I claim is:

1. In a mop, the combination with acylinder and piston working therein, of a mop head connected to the headend of the cylinder and having a water port, and a scra er blade attached to the mop head and havlng a water port, said scraper-blade arran ed to draw away from the mop head durlng the movement thereof inone direction and to fold thereunder during a reverse movement of said mop head, said two water ports,

' when the scraper blade is folded' under the the water ports in the mop head when the scraper blade is folded thereon.

3. In a mop, the combination with a cylinder and piston working'therein, of a mop head connected to the head end of said cylinder and having transverse water ports, a

scraper blade attached to said head and having water ports adapted toregister with the water ports of said mop head,the said cylinder having a projecting tubular stem aifording a handle, and said piston having a rod project+ ing' through said tubular stem, so that its outer end may be engaged to operate said piston. 4. In a mop, the combination with a cylinder and a piston working therein, said cylinder having a tubular stem aifording a handle and said piston having a rod extending through said stem so that it may. be engaged to operate saidpiston, a tubular mop head intermediately attached to the head end of said cylinder-and in communication'with the interior thereof, said head having transversely spaced water ports, a

- rubber scraper blade attached to the top of said mop head at its upper edge and having water ports adapted to registerwith the waterports'of said mo hea e 5. In a mop, the com in'ation' with a cylinder and a piston working therein, said cylinder having a tubular stem afiording a handle and sald piston having a rod ex tending through said stemsothat'it may be engaged to operate said piston, a tubular mop. head intermediately attached to the head end of saidcylinder and in commun'i-' cation with the interior thereof, said head having transversel spaced water ports, a rubber scraper bla e attached to the top of said mop head at its upper: edge and having water ports'adapted to register with the wa-" ter ports of said 1110 headQand' a flexible auxiliary scraper bla e attached at its upper edge to the upper edge of the main'.scraper blade, terminating in its lower edgeshort of the lower edge of said main. b lade,'and having relatively. large wate' ports that register with the water ports o1:'"said main' blade,

whereby, water collected by said two scraper. blades may be drawn into-the cylinder, said two scraper blades adapted to fold, the one upon the other and upon the tubular mop head. v y

In testimony whereof I .afiix my signature in presence of two witnesses;
